MACHINE FOR PRINTING SAMPLES ON TEXTILE FABRICS.

SFECIPICATION forming part of Letters Patent No, 339K548, dated April 6,1886.

Application filed September 4, 1835. Serial Xo. 1.0,137. (No model.)Patented in England April 26, 1884, No. 6,838.

T 0 all whom it may concern.-

Be it known that I, NVILLIAM Burr-Inn, a subject of the Queen ofGreatBritain, residing at Manchester, i n the county of La ncaster, England,have invented a new and useful Machine for Printing Samples on TextileFab rics, (for which I have obtained a patent in Great Britain, No.6,838, bearing date April 26, 1884,) of which the following is aspecification.

My invention relates to improvements in printing samples or patterns ontextile fabrics of designs from the engraved copper rollers used inprinting-machines.

The process of sampling is at present extremely costly, as the sametrouble and care must be taken in adjusting the printing-machine toobtain one or two yards of printed cloth as a sample from one or a setof engraved copper rollers as are required for printing any number ofpieces.

It is essential in calicoprinting that one set of engraved copperrollers making up one design should, by the use of different colors andcombinations, produce a great variety of effects. A separate trial mustbe made for each effect, and each trial involves a readjustment of themachine for the sake only of striking off one or two yards of cloth;hence great delay and costare incurred, and fewer samples orcombinations are made than are pos sible and desirable if the process ofsampling were inexpensive and simple.

The principal object of my invention, therefore, is to simplify andcheapcn the process of sampling; and I attain this object byconstructing a special machine for the purpose, wherein I am enabled toprint samples of designs from the engraved copper rollers without thenecessity of first mounting the rollers on solid mandrels, and thenputting theminto the ordinary printingmachine.

And in order that my invention may be fully understood and readilycarried into effect,l will describe the accompanying sheet of machine,the shaft of the roller a being supported in adjustable bearings a,secured to two arms, a pivoted at a to the standards of the frame I),and at their outer ends jointed to rods c, by which they are connectedto horizontal levers d, pivoted at d to the frame b and weighted at (EThe pivoted levers d are operated by means of rods e, which have avertical reciprocating motion,and are secured below to the levers d, andcarry at their upper ends anti-friction bowls e,which restupon and areoperated by cams f, keyed toa camshaft, g. A spur-wheel, g, is fixed onthe cam-shaft g, and is driven by a pinion, h, secured on thedriving-shaft h, which receives its revolving motion by means ofaclutch, i, free to slide on a feather-key bedded in the shaft h, andmoved by a forked lever, 2 into or out of gear with clutch-teeth formedon the boss of the drivingpulley h, which is loose on the shaft h, andis driven by the strap It. The forked ends of the lever i rest in agroove in the clutch i, and the lever is secured at the other end to ashaft, t, which may be turned in either direction by a hand-wheel, Therods 6, therefore,always receive their vertical reciprocating motionwhenever the clutch i is engaged with the clutch teeth on thedrivingpulley h, and the camshaft g revolves, and as one of the rods 6is slotted at e" to admit one end of a lever, j, pivoted at the otherend,j, to the frame I), this lever j is also actuated as the rods 6 riseand fall.

To the lever j is jointed one end of a rod, 75, the other end of whichis jointed to one end of a lever, Z, fulcrumed at-Z. Also fulcrumed at Zis a clutch-lever, m, the forked ends of which rest in a groove in adouble clutch, a, mounted and free to slide on a feather-key in a shaft,0, and engage with one or other of two bevel-wheels, p p, loose on theshaft 0, and both gearing into a carrier-wheel, q, fixed on a stud, g,which is supported in a bearing in an arm or bracket, g, carried by theframe b.

On the boss of the bevel-wheel p is secured the spur-wheel 1-, which isgeared with and receives motion from the spur-whcel g, which is drivenby the pinion h, as already described, whenever the clutch "i is engagedwith the drlving-pulley h and in this manner whenever the spur-wheel ris driven the bevel wheel p revolves with it, and by means of thecarrier-wheel q drives the bevel-wheel p in the opposite direction. Theshaft 0 is supported in suitable hearings in the frame b, and has keyedon its inner end a spur-wheel, s, which gears into the spur-wheel t,secured to the shaft of the roller a, and so drives the roller a in onedirection, when the clutch n is in gear with the bevel-wheel p and inthe opposite direction w henthe clutch is engaged with the wheel 19.

Fixed on the shaft of the roller a is a pulley, z, which is driven by astrap from a pulley, .2, on a counter-shaft, a, to turn the roller a andbring onto the latter a fresh supply of cloth for printing anothersample after a pattern has been completed. The engraved copper roller uis supported at each end on a pair of anti-friction rollers, '0, free torevolve in bearings o, secu red to a transverse beam, 1), which isbolted to the frame I). The position of the engraved roller u isadjusted circumferentially by the use of a pitching pin or pointer, to,and the engravers pin-mark on the roller and endwise by screws 20, whichpass through side plates or brackets, 10, and have plates 10 secured totheir inner ends. These plates 10 bear against the ends of the engravedroller a, and when the roller is in the proper position for printing itis secured in its place by the lock-nuts 10 To give the color to theengraved roller u, a small color-box, 3 with a furnishing roll errevolving inside is carried by a bracket secured to the side plates, 10,and. a doctor or cleaning blade for removing the surplus color is alsoemployed. 1

The drawings represent the various parts in the position they occupywhen the roller a is raised out of contact with the engraved copperroller u and the machine is at rest. When the clutch i is moved by meansof the hand-wheel i into gear with the clutch-teeth on the revolvingpulley W, the shaft h and pinion h revolve, and motion is given to thewheel 9, and thus to the cam-shaft g. The cams f turn with the shaft 9in the direction indicated by the arrows, Fig. 1, thus allowing theweighted levers (Z to draw down the rods e and anti-friction bowls e,and as the rods 6 are drawn down the end of the leverj,resting in theslot 6 is depressed, thus actuating the rod 70, lever Z, andclutch-lever m, and moving the clutch a into gear with the revolvingwheel 19. In this manner motion is transmitted by the clutch n to theshaft 0 and spurwheel 8, and so by the wheel t to the roller a. As theclutch a is moved into gear with the wheel 1) in the manner described,the connecting-rods c, which are actuated by the movement of theweighted levers d, raise the outer ends of the arms a and so bring theroller a into contact with the engraved roller 10, and as the roller aturns it drives the engraved roller u by friction, and the pattern isthus printed on the cloth stretched round the roller a. As long as theclutch. dis in gear with the driving-pulley h, and the motion of theshaft 9 continues, the cams f alternately rise and allow the rods 0 tobe lowered, by which means the clutch n is moved automatically from thewheel 1) to' the wheel 1), as already described, and the motion of theroller a and other parts of the machine is reversed, the roller a beingvraised out of contact with the engraved copper rolleru and turned backto the exact position from whence it started.

If the design requires more than one engraved copper roller, the secondone is placed on the anti-friction rollers o,the first roller, 10, beinglifted out of the machine. The second roller is adjusted by means of thepitchingpin a, as before described, to the exact position to fit itsengraved figure into theimpression taken from the first roller,and colorfrom a fresh box is supplied to the roller. The roller a is then loweredby the arms a and the partial revolution is again made, as before, toprint from the engraved roller. A third engraved copper roller may betreated in a similar manner, and so on to any numher. On each return orreverse motion of the roller a it revolves the exact distance, as inprinting; but when the pattern is completed the return is double ormore, the roller a being driven by the pulley a, so that afresh surfaceof cloth may be brought into position ready for printing from anotherset of rollers or different colorings off the same rollers.

The simplicity of adjustment of the rollers one after the other to fitexactly, the absence of the ordinary printingmachine and largecolor-box, and the rapidity with which the motions are automaticallymade in printing and reversing, enable alarge number of combinations andcolorings to be made, and many patterns or samples produced in a shorttime and with a small quantity of cloth as compared to that required inthe usual way in the ordinary printing-machine.

Having thus stated the nature of my invention, and described the mannerof performing the same, I declare that what I claim as my invention, anddesire to secure by Letters Patent of the United States, is-

1. In a sample-printing machine, the combination, with the pivotedsample-roll arms and the driving mechanism of the sampleroll,substantially as described, of the cam mounted on a shaft geared to thedriving-shaft and the weighted pivoted rod-connections,substantially asdescribed, of said arms actuated by said cams, together with thedriving-shaft, reversing-gear, and the pivoted.- rodconnections betweensaid latter gear and the said weighted rod-connections, substantially asand for the purpose set forth.
